(c1. ass-a2) The present invention relates to improve ments in mechanism for registering the operations of ticket issuing machines of the type adapted for use in connection with betting on I races or similar contests where the betting odds" are calculated by the so-called "parimutuel" system.

will Patent Number 2,150,761, issued on March 14, 1939, to Harry 0. Craig and Alfred W. Pride, 1 entitled Ticket printing and issuing machine, there is described a machine for printing and issuing tickets bearing all information necessary to identify a particular race or races and particular entries, in favor of which a bet is made together with means for registering the total number of tickets issued on each entry and totalizing the tickets issued for the entire race.

The said patent discloses a mechanically operated counting device contained by the ticket isa suing machine for registering the number. of tickets sold on eachentry and for,registering the totalsales for each race. There is also disclosed diagrammatically therein a system comprising electrically actuated mechanical counters for effecting the same registration and totalization at a point remote from the machine. Each of these systems is complete and adequate in its application to a single ticket issuing machine of the kind disclosed. The problem of rapid and accurate registration of ticket sales, however, is rendered complex by reason of ,the fact that large numbers of machines are necessary to'issue tickets in the quantities and at the speed required to accommodate the usual patronage.

Further complexing the problem is the fact that it is customary that the machines be arranged in remotely spaced groups making mechanical connection between more than a very limited 0 numberof machines impractical.

The registration of 'all tickets issued' for all entries of a race and of the total ticket sales, irrespective of the number of machines issuing tickets, is essential to the practice of the pari- 45 mutuel system, wherein betting odds aredet'ermined by computations based upon this data.

It is the object of the present invention to improve in general the operation of a group of ticket printing and issuing machines and to pro vide a system for the synchronization of a group of such machines to the end that electrical mechanical counting of .the operations of the individual machinesmay beeilected rapidly, through relatively simple mechanism, accurately and 5 without interference between machines in the same group, even though the operation of more than one machine be instigated simultaneously. It is a further object of the present invention 'to provide a system in which the operation of several classes of machines may be recorded separately, without interference and reduce to a minimum the time required for the individual counting operation of any one machine so that as many as possible machines may be accommodated on a single counting circuit.

While the invention is exemplified herein as applied to machines used for printing and issuing tickets, it. will appear that the principles thereof are adaptable to the counting and registering of various other kinds of operations, as the ticket printing operation in itself forms no part of the present application.

One form of the invention is exemplified in the accompanying drawings, to which detailed reference is made in the following specification. In the specification further of the objects and advantages of the invention are made apparent.

In the drawings-- Figs. 1 and 2 are a wiring diagram of a system embodying the present invention with certain mechanical elements diagrammatically illustrated therein, the bottom portion of the sheet in Fig. 2 being a continuation of the top portion of the sheet in Fig.1, and

. Fig. 3 is an enlarged wiring diagram of a por-' tion of a system of the kind shown in- Figs. 1

and 2 and illustrating the application of a safety switch circuit thereto.

The drawings are diagrammatical and illustrative of the principles upon which the invention may be practised rather than of a complete system, it being understood that the number and classifications of machines in any system are determined by the-particular requirements of the course or track where the system is installed. It will appear, as the description proceeds, that the invention is readily adapted to the varying conditions and requirements of different courses.

As a premise to the description of the invention as it is illustrated in-the' drawings, let it be assumed that there are, as usual, three general classes of bets which maybe made in favor of any entry of any race. These classes are known as {win, place and show." To win, an

entry must finish first; while to place, the entry must finish first or second; and to "show,"

theen'try may finish either first,'second or third.

Inasmuch as the odds payable in any of these three classifications are based upon the amount of money placed upon all entries under that particular classification, it is apparent that three entirely separate systems must be operated to produce three separate results. The present invention contemplates the use of three substantially identical systems for thisypurpose, which systems may be to some extent mechanically coo'rdinated, but which must be maintained separate and independent with respect to impulses in the electrical circuits which control the counting and totalizing. the three systems are identical in principles of operation, only one will be described in detail, the description of the others being suflicient only to illustrate the manner in which the three may be correlated.

Referring now to the drawings and particularly to Figs. 1 and 2, there are illustrated two typical groups of ticket-issuing machines. Each of these groups is driven from a separate drive shaft, said shafts being indicated at and 2|, and the machines of each group are. divided into classifications of win, place and show. The

win machines are indicated by the reference numeral 22,-theplace machines by the numeral 23 and the show machines by. the numeral 24. While there are but three wirr machines in each, group and one each of the place and show machines, it is to be understood that the drawings are simply illustrative of the principle,

select a counter circuit corresponding to that entry. Such circuit selectors are illustrated diagrammatically at 25 in Figs. 1 and 2 and should be of a non-bridging type, one suitable form of whichis disclosed in the said patent. Electrical energy from a common source, such as a battery 26 (see Fig. 2), is can'ied by a conductor 21 to banks of electromechanically actuated counters 28. Each bank of counters 28 comprises ten counters numbered from "1 to 10 to be actuated selectively upon the sale of tickets on correspondingly numbered entries and a total counter marked T to be actuated upon the sale of a ticket upon any entry.

A variable resistance 29 in the total counter circuit and a similar resistance 30 in the circuit of the numbered entry counters permit balancing of the electrical constants of the circuits for most eflicient operation of the electromagnets which actuate the counters. Each of the counters, 1 to 10" inclusive, is connected bya separate conductor, as illustrated, with the respectivecontact points of the circuit selector 25; A sliding finger 3| engageable selectively with the contact points of the selector 25, is connected with a switch 32 com-prising a-pivoted arm 33 which may close to complete a circuit through a conductor l2 to the battery.

A;conductor l l connects the totalizing counter 'If..with a-switch 34, which also includes. the pivoted arm 33. Closing'of. the switch 34 by the arm 33 completes the circuit to the battery 26 through thecommon conductor l2. Condensers 35 and 36 are placed in parallel with the switches 32 and'34 to reduce arcing at the contact points of these switches. The switches 32 and 34 are closed by any suitable mechanical means, as, for

example, a rotatable cam 31 which is designed and driven by the ticket-issuing mechanism to effect closing of the points to close the entryv counting and totalizing circuits-at an instant predetermined with relation to the cyclic operadisposed at'difierent positionswith respect to. 10

the cam. For example, as illustrated in the machines on drive shaft 2|, the breaker points are disposed 180 apart so that at a given cam speed of 100 R. P. M., the entry counter circuit will be energized .3 second in advance of the 15 tota counter circuit.

This structure necessitates obvious modifications of the timing schedule but for the purpose of simplicity, the timing of the impulses over the counter circuits will be considered as-though they were initiated by the 20 device previously described and illustrated in the machines driven from shaft 20.

In order to avoid any possibility of two machines in the same class sending simultaneous counter circuit and to ensure against simultaneous operation of any machines on the same drive shaft, which operation might iinpose a momentary overload on such shaft, the machines are synchronized for successive operation with rela- 30 tion to the rotation of the drive shaft in the manner best illustrated in Figs. land 2. In Figs. 1 and 2, two drive shafts 20 and 2 i are illustrated as driving groups of machines 22, 23 and 24 of the win," place and show classes respectively. 35

These drive shafts may be continuously .rotated by any suitable drive means capable of causing their synchronous operation at approximately constant speed. A driving connection is formed between the drive shafts and each machine, pref 40,

erably in the form of a chain 38, to ensure the maintaining of 'predetermined phase positions of, the driving clutch members of the ticket-issuing machines.

For convenience intiming the points of engagement of the clutch members and the impulse initiating contacts of the switches 32 and 34 in the totalizing counter circuits, it is preferred that the driving connections be of one to one ratio. With this ratio one revolution of the B0 drive shaft results in one revolution of the driving cutch members and one complete cycle of the printing mechanism of thevmachine after engagement of the driving and driven members of the clutch. This ensures the maintaining of the contact timing cams of the machines in predetermined phase positions.

While any suitable type of drive connection may be usedin place of the chains 38, chains are preferred for convenience in mechanical instal-' lation and operation. By using driving and driven sprockets with an even number of teeth on each and with the sprockets center distances established 'at an integral number of chain pitches the effect of chordal pitch on chain drive operation is of minor importance and the driving clutch members maintain substantially their proper phase relation with respect to the main driveshaft throughout all parts of the revoluload on the main drive shaft throughout its revoshafts .fl and ii in the same relative'position lutlon and in order that the time contacts may be properly adjusted to initiate impulses over the electric counter circuits which will not overlap or interfere with impulses from other machines, a protractor I! is mounted on the drive shaft and cooperates with a stationary pointer visibly to indicate the phase position of the drive shaft.

Assuming that there are but three machines of-v each of the -win," "place and show" classes on one drive shaft, thus making nine machines in all driven by said shaft, the point of clutch engagement of these "machines could be so adiu'sted that each machine will be actuated at as determined by the protractor on the shaft,

. from the point where the next successive machine is actuated: Depression of the operating handle of any one of these machines will, therefore,

result in the same relative point of engagement of its clutch to the main drive shaft, irrespective of the exact position v f the drive shaft when the operating handle the machine is depressed. Thus, should it occur that .all of the nine machines on one drive shaft were actuated simultaneously to print and issue a ticket they would operate successively at equally spaced intervals throughout a single complete rotation ferred to, of the single cycle, single dog type which releases itself automatically after a complete rotation. It should be understood, however, that the invention is not limited to any particular type of clutch but that various kinds of clutches may be used instead of the one described.

For example, clutches engageable at two or more points in one revolution ofthe' driving member may be used to reduce the time lapse following initiation of the ticket-issuing operation by depression of the lever which conditions the clutch for engagement. This of course calls for a rearrangement of the timing of the machines in the system relative to the drive shaft, and as there must be an electric impulse channel to the counters allotted to each machine for each point of possible clutch engagement, the number of machines that can be operated with a given counter is reduced by the more rapidly operating type of clutch under the present system;

As previously stated, the two drive shafts 20 and fl and as many other similar drive shafts as may be used in the system, are driven at the same rate of speed and synchronously. As each drive shaft is provided with a protractor I! to 7 indicate its phase position and as the several machines on each shaft are timed through their clutches to operate at equally spaced intervals,

throughout a complete rotation of the shaft, it is simply necessary to regulate the phase positions 1 of the shafts to insure against simultaneous operation of two or more'machines'on different shafts.

The principal reason for employing more than a single driveshaftis that, for convenience in' issuing tickets, the machines are often placed in groups at different locations in the vicinity of the racing track. The spacing'of these groups of machines is too remote to permit practical direct mechanical driving connections between the shafts.

For the purpose of maintainin the main drive under all conditions as if they were in tied together through gears and would therefore rotate in the same relative positions irrespective of conditions, any-brown system of synchronous 5 motors may he used; and any means for establishing the relative positions of the shafts either at rest or in motion may he used."

Because of the advantage of ore-setting the impulse initiating contacts in proper o erating 10 sequence, phase 'and duration under static or extremely slow rotational conditions of the drive shaft, the preferred method of driving the shafts synchronously for thepurpose of my invention is that illustrated in Fig 1 of the drawings where a system of motors known as the Belsyn or "Synchro-tie" system is shown. A detailed discussion of the theory of these systems is unneces- I saw in the present description as the system itself is.well known as a medium to transmit motion electrically between two or more "points which cannot conveniently be interconnected mechanically. v Briefly, the system may be considered as two or more identical three-phase wound rotor induction motors. The stator windings are excited ages will be exactly opposed so that no current a will circulate in the secondary windings. For other positions a current will circulate in the rotor windings and torque will result, tending to -turn the rotors to that position where the voltages are again equal and opposite. If, there'- fore, one rotor is turned, the other rotors will tend to'assume exactly the same position.

Referring again to Fig. 1 of the drawings, there is shown a receiver motor 48 for driving each of the shafts 20 and 2|. The stators of these motors are connected witha common three-phase circuit 4, which circuit also excites the stator of a transmitter or generator motor 41 and supplies energy to a synchronous driving motor 0. A shaft 49 connects the driving motor with the rotor-of the generator 41 and this rotor is electrically connected with the rotors of the receiver motors I! by means of a three-phase circuit II.

The motor 48, therefore, drives the generator 41 which, in turn, actuates through induction the receiver motors 45 to rotate the shafts II and II. As rotation of either one of the shafts 2.

or fl will rotate its associated motor I and,

through induction, the other motors ll and the I mechanically geared to each other.

Reduction gearingindicated at 5l*is interposed between-each of the shafts and its motor 45 to cause the shaft torotate at a speed prac-' tical for the operation of ticket-issuing machinery. Similar reduction gearing, indicated at 52, may be interposed between the shaft of motor 4' and a countershaft 53 which may carry a master protractor, as shown at N.

Assuming that the single cycle clutch engaging at predetermined phase position is used in. the system and that there are four drive shafts like those shown at II and II, each driving three machines of the win" classification, the twelve 15 win machines must all register upon the counters of the win totalizer and the timing of these machines would be as follows:

Determining the position of the drive shafts fromtheir respective protractors which will .be set for identical readings, with the synchronous motors energized and so locked in proper phase position, the first win machine will be adjusted to initiate an impulse over the counter circuit at 30 drive shaft protractor reading, the second at the third'at 90, and so on, the twelve machines being equally separated as to impulse timing throughout a full revolution of the drive shaft. The positions of clutch engagement of thesem'achines need not coincide with the timing of the electric impulses, as the timing contacts which control the impulses to the totalizers may be adjusted to accurate phase position, independently of the position of clutch engagement. I

As there need be no particular coordination between the mechanical starting times of the machine and the times at which the electric impulse are initiated, it is conceivable that the timing may in some instances be such for a particular machine that its electric contacts are .closed while single totalizeris limited by reason of the factthat some time is required for-theoperation-of the mechanical counting devices used in the totalizers. If the drive shafts are rotating at a:

uniform-speed of 100 R. P. M., a single revolution occupies .6 second, while one-twelfth of this time or .05second isrequired for 30 degrees of each revolution which is the time ailotted'to, each ,of the twelve machines.

Assuming that the breaker points 34, which complete the circuit to the totalizer, are closed for 14 degrees of the cycle and open for 16 degrees of the cycle, this allows approximately .0233 seconds time to advance the electromag netically actuated counter one step and .0267 seconds time for the counter to return to a position preparatory to being advanced by the next subsequent impulse. Thus a'total time of .05 second, which is equal to the time occupied by rotation of the drive shaft through 30 degrees is allowed for the operation of the counters. It may be stated that this and even greater speeds may reasonably be expected from certain commercially available types of counters. 7

It is possible, however, that the timing just described may be difllcult to effect because of non-uniform speed of the timing cams 31 which might result fromv such causes as back lash in the driving chains or by variations in load. If such non-uniform speed reduced the period that the contacts were closed ,to .020 seconds time or about 12 degrees of drive shaft rotation the interval of current flow through the counter might be insuflicient to effect its operation and that impulse would not be registered. On the other hand, if the intervening period of open contacts were reduced to .0233 seconds time or 14 degrees of drive shaft operation, one machine might send itsimpulse over a circuit and to a counter just energized by a previously operated machine before the counter had returned pair of breaker points 60 bridged by a condenser GI and connected in the battery circuit by a conductor 62 leading directly to the battery 26a (shown as an alternative to the battery 26 to illustrate this circuit), and a conductor 63 leading to the wires I! which return to the battery through the circuit selectors and counters. A twelve-point cam 65 fixed to the counter-shaft 53 for rotation therewith is designed to effect opening and closing of the breaker points at more accurately timed intervals. With the twelve-machine system described above, the cam will close the circuit for 14 and'openthe circuit for 16, alternately, The timingof. the machines in the system will then be varied. For

example, the closed contact time of the machines may be increased from 14 to 20".. The first machine. would' then operate to close the; circuit from about" 357? or-3 to 17'drive shaft position.. With the accurate timing contact closing the same circuit from 0 to 14, there is a 3 tolerance for error at either the opening or closing period, which is more than suflicient to overcome any possible error due to' non-uniformity in drive shaft or switch operating cam speeds. In the drawings, this accurate timing feature is illustrated only in connection with the "show" totalizer and a separate battery circuit is used. It is to be understood that thisfeature may be used on any or all of the win, "place and show" totalizers, and that a single battery all of the tomay be used to supply energy to tallzers.

Because the machines and the bearings of the main drive shaft, as well as other parts of the system, are subject to accidents which might place an excessive loadon the motor driving the shaft and because that motor might be pulled out 01.,synchronism with the generator and other motors, resulting in disturbance to the timing of electric impulses from machines driven thereby, it is desirable to have some means for automatically disconnecting the motor under these conditions. It is likewise desirable to disconnect the totalizer circuits associated with the machines driven by the disabled main drive shaft and also to render the individual machines driven by the shaft inoperative.

A preferred structure for means for disabling one of the drive shafts, together with the machines-driven by it and the circuits to totalizers connectedwith said machines, is illustrated in Fig. 3 of the drawings. Fig. 3 illustrates a some- .what abbreviated system employing but three greases two-thirds of the pull-out current of the synchronous motor 45. Assuming that the current in the lead, which includes the switch under motor operation, has a normal rating of one ampere, and that the pull-out current oi. the motor is five amperes, the relay I0 is set to operate and close its switch II at 3.5 amperes. A trip coil 12 is included in the same circuit as the switch H, to be energized by closing of the switch I l The trip coil 12 operates a multiple switch comprising a plurality of pivoted levers I3, all connected with an armature 14 which is moved upwardly upon energization of the trip coil 12. The three uppermost pivoted contact levers I3 0! the multiple switch control the rotor circuit of the motor I! so that upon the event of a current of amperesfiowing through the coil of the relay 10, the relay switch II will be closed to energize the trip coil I2 and to open the motor circuit, thereby causing the main drive shaft 20 to come to rest promptly upon the imposition of an over-load on the motor 45.

The three-lowermostpivoted contact arms 13 of the multiple switch control the win,': the place and the show" totalizer units through switch circuits which include the wires II, II and II, respectively, leading to the wires I! of these circuits, and the wires 10, I! and 80, respectively, leading from these circuits. Consequently, upon energization of the trip coil 12, which occurs upon over-loading of the motor 45, the circuits to the totalizers are broken and no impulses may lie-initiated by the machines driven by the shaft 20 to affect these totalizers as long as the motor is disabled and the multiple switch is open. This is desirable because should the over-load conditions cause the main drive shaft to come to rest suddenly with one of the totalizer timer contacts closed, the operation of the totalizing system would be disturbed.

The multiple switch may also control a lock-out circuit of the machines in the grcup'driven by the disabled drive shaft. In the above referred to Patent Number 2,150,761 there is described a relay-actuated lock operable from a remote point to prevent operation of any of the machines at any but the proper time and which is intended to be controlled by an ofllcial by means of a switch included in the circuit which energizes the relays.

failureof anypar't of thejmechanism whichrequires disabling of the drive shaft bycutting outthe motor the operating handles of the ma- .chines will be automatically locked against -.chines, not having their operating levers in a operation. v M a With the use of this multiple switch which is actuated uponoover-loading of the synchronous motor 45, the lock-out relays of all of the madepressed position upon opening of the motor switch, would render these machines immediately inoperative. The totalizing circuits connected to these machines would be opened so that the timing contacts of any machine in operation at the instant that the motor was cut out might come to rest in their closed position without of the totalizing systemis directed to the opera- Thustheerrorsoftotalisingresultingiromsuch aiailureoi'agroupotmaehineswouldbereduced to a minimum.

The above description stresses the driving of groups of machines iromacommonshaitby 8 one motor. This may be economical under certain circumstances. However, the system may be applied to individual synchronous motors for each printing-issuing machine.

The present invention is also capable oi use to register the, sales of so-called"acroas-t heboar or combination tickets. A combination ticket is one which represents a bet equally divided on'a'n entry to win, place or show. For

example, a $6.00 combination ticket on an entry is equivalent to a $2.00 bet to win, a $2.00 bet to place, and a $2.00 bet to show. To provide an accurate total of sales on an entry to win, to place and to show, it would be necessary to record separately the sale of combination tickets on the entry, then divide the total combination sales by three, and add the resulting one-third to each of the win, place and show totals.

To avoid the necessity of such calculations and the loss of time incident totaking several readings for each entry, and performing the necessary calculations, the sale or combination tickets may .be recorded directly IP the counters which reghter straight bets.

. This may be accomplished by mechanical connection between the operating levers of three machines so "that they will be actuated simultaneously by depression or the operating lever of one of them, which will be, termed the control-machine. In this event, three machines are connected, one with each of the win, place, and show totalizers, by means of their circuit selectors II,

in the usual manner.

,In order, then, to issueand register the sale or a combination ticket, three selectors are set to the entry upon which the ticket is to issue. The operating lever 01' the control-machine is then actuated to print a ticket and all three machines operate, with due regard to timing, to initiate impulses to the .wln, place and show counters for the selected entry. The value registered on each counter will be one-third the face value of the combination ticket. v

Although the above description of the operation tion or electrical magnet counters by its initiation I of electrical impulses, this invention is not limited-to theuseoisuchcounters. Theimpulses initiated by presseswhen so set up might be employed to perform iunctiohs other than those specifically described herein. I

Other modifications than those herein illustrated and described may be practiced within the scope oi the invention'as it is defined in the ap-- pended claims.

Having thus described my invention, what I claim anddesire to secure by Letters Patent isof clutch engagement. I
